7.8.2. Config - Ambig-Word: Ambiguous Keypad with Word-Level
Disambiguation
The Ambig-Word configuration looks exactly like the Ambig-Char configuration, but it guesses at letters in a
different manner. Rather than typing in individual characters and recoding them as necessary, you will spell
out a complete word and then recode the word guesses that Palmtop makes. This is called word-level
disambiguation. For example, to type out "dog," select the
def , mno , and ghi buttons, then look in the Editor
Window to see if the system guessed the correct word. In this case, Palmtop guessed correctly. But what if
you had meant to type out "fog" - a word that uses the same keys? You would have to select the
Recode
key, after which "fog" would appear in the Editor Window. You will need to do fewer total recodes with word-
level disambiguation because the Palmtop software is better at guessing whole words than it is at guessing
characters.
The Palmtop software can often guess your correct word on the first try or after several recode attempts. In
the case of proper nouns that are not in the dictionary, you might have to correct the individual characters
like you do with the
Ambig-Char configuration. If the right word does not appear after three or four recode
attempts, enter "character-by-character" mode by selecting the CBC button (which will appear only after you
select the Shift button). You will switch to a page with three buttons labeled Recode , Accept and Exit and the
first character of the word will be highlighted in the Editor Window. If the character is incorrect, select the
Recode button until it is right. Once you have selected the correct letter, select the Accept button to move
onto the next letter. Repeat this process until the whole word is correct, then select the Exit button to return
to the basic interface. Palmtop will update its guess when each character is corrected, so you may be able to
exit character-by-character mode without having to correct each individual character.
The Ambig-Word interface can take some getting used to. As you select new letters, the characters that
appear in the Editor Window will change to reflect the new information. You should try to ignore the Editor
Window until you have spelled the entire word.

Note: It is recommended that you add common proper nouns, such as places and names, to the
dictionary. Doing so will minimize the times you need to enter CBC mode, and should help
speed up your communication when using this configuration.
